Evaluation of a single-dose HPV vaccine strategy for promoting vaccine, health, and gender equity.

Abstract

Although several countries have adopted a single-dose human papillomavirus (HPV) vaccination strategy, many other countries continue to include multiple doses in their vaccination programmes. There are ethical reasons to transition to a single-dose strategy. We discuss how a single-dose HPV vaccination strategy advances equity in three dimensions: vaccine equity, health equity, and gender equity. Adopting a single-dose strategy eases pressure on vaccine supply, lowers programme costs, and is easier to distribute. This change facilitates vaccine procurement and implementation programmes (contributing to vaccine equity) and reaching hard to reach people or populations (contributing to health equity). A lower number of cases of HPV-related diseases that stem from greater vaccine distribution reduces the burden on women, who are at a higher risk of HPV-related disease or who act as caregivers, which prevents them from accessing opportunities that contribute to their empowerment (contributing to gender equity). Thus, pursuing the single-dose HPV vaccination programme strategy is ethically desirable.
